GRILLE.

Continuation of application Serial No. 48,401, filed August 5, 192 5.This application filed December 21, 1927. Serial No. 241,605.

This invention relates to grilles and particularly to those grilles usedfor doors and Windows, and is a continuation of my application, SerialNo. 48,401, filed August 5,

There is on the market today a large numstable, noisy and expensive tomanufacture.

The primary object of the present invention is the provision of animproved window and door grille.

Other objects of my invention are to produce a grille for doors andwindows which (1) will be adapted to fit windows and doors of variouswidths (2) will be adapted to be attached to the outer surface of thedoor or window or (3) to the opposite parallel surfaces, (4) will bestiff throughout the main body of the outer frame members, the latterbeing capable of being bent adjacent the fastening, (5) will be cheap ofmanufacture, (6) easy of installation and (7) will not rattle with themovement of the door or window.

.parent, to those skilled in the art, from a reading of the completespecification and claims.

Referring to the drawing wherein Ihave illustrated an embodiment of myinvention, Fig. 1 is a fragmental view of a-door such as. a screen doorand showing my improved grille attached thereto.

Fig. 2 is a fragmental view of a corner of my invention. as it is placedon the market. Fig. 3 is a cross sectional view on thelin'e 33 of Fig.2. i

Fig. 4 is a cross sectional view on the line 4-4 of Fig; 2. V

Fig. 5 is a crosssectional view on the line 5-5 of Fig. 2. a

Fig. 6 is a cross sectional view on the line 66 of Fig. 2.

Other and further objects will be ap- Fig. 7 is a fra mental viewillustrating a method of attac ment to the inside of a. frame member ofa window or door.

Like reference characters refer to the same or similar parts throughoutthe views.

The numeral 10 designates the frame of a door or window to which myinvention is applied. The numeral 11 designates the upper and lowersupporting members which provide the main support for the main body ofthe grille. This main body portion is hereinillustrated as in the formof a woven structure forming a grating and having vertical strips 12 andhorizontal strips 13. These strips are shown as woven with a basketweave, the individual strips being of a wavy shape'to add stiflnessand-strength to the device as a whole.

In order to solidify. the grille, the body portion is preferably weldedat a portion or all of the crossing or junction points 14.

The supporting members 11 are of a U- shaped cross sectlon, in the openportion of which are received the u per and lower.

edges of the grating or bo y portion. The U-shaped body portion ispressed together upon these edges; to firmly hold the grat ing or bodyportion ofthe grille and the supporting) members together.

It is to It is to be also noted that because of the shape of thesupporting members where the edges of the grating or body portion arereceived in their respective folds, the supporting members, because oftheir open construction, act .as trussesand have a tendenc to preventbending of the structure as a w ole.

. Where, however, the two folds of the respective supporting memberscome together in the extensions 15, it is not necessary to have a trussaction and the supporting members 11 may be bent as shown in Fig. 7-toprovide an angular suppprting member15 by which the grille may attachedtothe inside'edge e noted that beyond the edges of. the grating or bodyportion, the supporting sire to have it understood that the showing of adoor or window frame 10. The parts 11, 12, and 13 in Fig. 7, correspondto the parts 11, 12 and 13, respectively, already described.

In using my improved grille, a series of openings 16 areprovided on theextensions 15 to allow for wide or narrow windows or doors. The frame 10illustrated in Fi 1 is of a medium size for this particular wi th ofgrille. As shown, the two inner holes 16 are not in use and the outerhole, shown in Fig. 2, is missing, due to the shortening of theextensions 15 by cutting or breaking. If broken off; the edge can bequickly smoothed with a file.

It is thus clear that I have produced an effective, cheap grille, onewhich is adapted for use on doors and wi ndows of various widths and isquiet and easy to install.

While I have illustrated in detail aproferred embodiment of myinvention, I ,de-

is merely illustrative and that modifications and changes may be madewithout departing from the spirit of my invention and within the scopeof the appended claims.

Having described my invention what I claim and desire to secure byLetters Patent, is

1. A grille for windows or doors compris ingtwo oppositely disposedsupporting members, a grating extending between the supporting members,the supporting members and grating being secured together at oppositesides of the grating, the ends of the supporting members extendingbeyondthe grating and being provided with a series of" securmg o enings. a 2.A le for windows-or doors comprising two oppositely disposed supportingmembers, a grating extending between the supporting members, thesupporting members being folded throughout their lengths on oppositesides of the grating to secure the grating to the supporting members,the ends of the supporting members extending beyond the grating andbeing provided with a series of' se'curing openings.

'3. A grille for windows or doors comprising two oppositely disposedsupporting members, a grating extending between the supporting members,the supporting members being folded on opposite sides of the grating tosecure the grating to the supporting members, the ends of the supportingmembers extending beyond the grating and being/of thinner cross sectionthan that portion of the supporting members between the ends and eachend being provided with a series of securing o enings.

4. A grille for windows or doors comprising two oppositely disposedsupporting members, a grating extending between the supporting members,the supporting members being bent to form a U-shape cross sectionthroughout the length of the edge of the grating, the latter beingsecurely held in the open U-construction of the supporting members, theends of the supporting mem- 'bers extending beyond the grating ingprovided with a series of securing openings, the U-shape supportingmember being pressed to close the opening at a point beyond each edge ofthe gratlng.

In testimony whereof I hereunto afiix my signature.
